THE SYMPATHETIC SYSTEM 369 



The latter is not yet well understood as to its physio- 

 logical effects. 



Dried or oily or glycerin extracts may be used. This 

 preparation was considered of value in temporary impo- 

 tence, in neurasthenia, senility and chlorosis of young 

 girls. At the present time there is considerable doubt as 

 to its efficacy. 



OVARIAN ORGANO THERAPY. The ovary has two 

 functions; one represented by laying eggs, the other an 

 internal secretion, which is largely due to corpus luteum, 

 but to a certain extent also by the interstitial part of the 

 ovary. This internal secretion acts chiefly upon menstru- 

 ation, and some of the phenomena at the beginning of 

 pregnancy, on the nutrition and development of the pelvic 

 organs and the development of the breasts. The extract 

 of the ovary in general causes stimulation and congestion of 

 the female genital organs and in this manner is antago- 

 nistic to mammary extracts. 



In organo therapy, this preparation is usually given in 

 tablets of the dried extract (25 to 50 centigrams) daily. 

 Sometimes it is given as a glycerin extract hypodermically. 

 The chief indications are those of ovarian insufficiency, 

 notably in women whose ovaries have been removed in 

 disturbances of the menopause and puberty. (Insufficient 

 menses, syndrome of adiposis genitalis of young girls), in 

 psychosis of genital origin, Dercum's disease, certain 

 cases of Basedow's disease and obstinate vomiting 

 of pregnancy. 



PANCREATIC ORGANO THERAPY. The pancreas has an 

 external secretion (pancreatic juice) and an internal 

 secretion whose function is to moderate the formation 

 of sugar by the liver. The chief function of pancreatic 

 extracts is to stimulate the function of the pancreas.
